Department / Org. unit Hierarchy report

Hi Team,

I am trying to pull a department / org. unit hierarchy report that rolls-up, for example if I am an IT analyst, under Service mgmt, ultimately rolling up to IT (org. unit) similiar to PPOME view.

I did try a FM (RH_STRUC_GET), but could not get the req. details.

Let me know if there is something like this, that I can use.

Thanks

RL
